Physical geography
The major natural regions are from north to south: the North German Lowlands, the Central Uplands and the Alpine Foothills with the Alps.
Geology
→ Main article: Geology of Germany
Geologically, Germany belongs to Western Europe, i.e. to that part of the continent that was successively annexed to the Precambrian consolidated "Ur-Europa" (Eastern Europe including a large part of Scandinavia, cf. Baltica) only in the course of the Phanerozoic by continent-continent collisions (mountain formations). The corresponding crustal provinces (bedrock provinces) are classically simplified as (Eastern) Avalonia (cf. Caledonian mountain building) and Armorica (cf. Variscan mountain building). The youngest crustal province is the Alpine-Carpathian orogen (cf. Alpine mountain building), in which Germany has a share only with the extreme south of Bavaria and which, in contrast to the other two tectonic provinces, represents an active orogen.
The present-day surface geology of Germany, i.e. the pattern of rock complexes of different ages and compositions, as often depicted in geological maps, only emerged in the course of the last 30 to 20 million years in the younger Cenozoic era and was decisively shaped by two events: the Alpidic mountain building and the Quaternary Ice Age.
The Quaternary Ice Age shaped the comparatively monotonous surface geology of northern Germany and the Alpine foothills with its moraine deposits and other accompanying phenomena of large-scale glaciations (cf. glacial series).
The surface geology of central and most of southern Germany is the result of significant rupture-tectonic uplift and subsidence, which can be traced back to the long-distance effect of the Alpidic mountain building. In this process, partly old (predominantly Palaeozoic), Variscan-folded bedrock complexes (slate mountains and crystalline) were uplifted from the subsoil and exposed over large areas (e.g. the Rhenish Slate Mountains, the Rhenish Crystalline Mountains). Rhenish Slate Mountains, Harz Mountains, Ore Mountains), in part the earth's crust sank and formed sedimentation areas that accommodated more or less thick Cenozoic sedimentary sequences (Upper Rhine Graben, Lower Rhine Graben, Hessian Depression, Molasse Basin). The tablelands with their unfolded Mesozoic stratigraphic sequences, dominated by Triassic and Jurassic (Thuringian Basin, South German stratigraphic country), occupy an intermediate tectonic position.
Relief
The geologically young folded mountain range of the Alps is the only high mountain range in which Germany has a share. The German Alps, which are almost entirely located in the federal state of Bavaria - a small part of the far northwest of the Allgäu Alps is in Baden-Württemberg - have the only mountain peaks above 2000 m a.s.l.. The summit of the Zugspitze (2962 m a.s.l.), which Germany shares with Austria, is the highest point in the country.
The German low mountain ranges extend from the northern edge of the low mountain threshold to the edge of the Alps and the Upper Rhine with Lake Constance. They tend to increase in height and extent from north to south. The highest low mountain peak is the Feldberg in the Black Forest (1493 m above sea level), followed by the Großer Arber in the Bavarian Forest (1456 m above sea level). The Erzgebirge, the Fichtelgebirge, the Swabian Alb and the Harz, which rises quite isolated as the northernmost of the highest German low mountain ranges with the Brocken at 1141 m above sea level, also have peaks above 1000 m above sea level. North of the low mountain range threshold, only a few mountains within the glacial terminal moraine ranges reach more than 100 m above sea level, the highest of which is the Heidehöhe in Schraden (Südlicher Landrücken in the Brandenburg-Saxony border region) at 201 m above sea level.
The deepest generally accessible land site in Germany is at 3.54 m below sea level in a depression near Neuendorf-Sachsenbande in the Wilstermarsch (Schleswig-Holstein). The deepest cryptodepression is also located in this federal state: at 39.6 m below sea level, it lies at the bottom of Lake Hemmelsdorf northeast of Lübeck. The deepest artificially created ground point is 267 m below sea level at the bottom of the Hambach open-cast mine east of Jülich in North Rhine-Westphalia.

Climate
→ Main article: Climate in Germany
Germany belongs entirely to the temperate climate zone of Central Europe in the area of the west wind zone and is located in the transitional area between the maritime climate in Western Europe and the continental climate in Eastern Europe. The climate in Germany is influenced, among other things, by the Gulf Stream, which makes the average temperature level unusually high for the latitude.
The average annual temperature, based on the normal period 1961-1990, is 8.2 °C in the national area average, the average monthly temperatures range from -0.5 °C in January to 16.9 °C in July. The mean annual precipitation is 789 millimetres. The mean monthly precipitation ranges from 49 millimetres in February to 85 millimetres in June.
The lowest officially recognised temperature measured in Germany was -37.8 °C; it was recorded in Wolnzach in 1929. The highest temperature so far was 41.2 °C and was measured on 25 July 2019 in Duisburg-Baerl and in Tönisvorst on the Lower Rhine.

Waters
Of the six rivers with the largest catchment areas, the Rhine, Elbe, Weser and Ems drain via the North Sea and the Oder via the Baltic Sea into the Atlantic, while the Danube flows into the Black Sea and thus hydrographically belongs to the Mediterranean. The catchment areas of these two systems are separated from each other by the main European watershed.
The Rhine, which originates in Switzerland, dominates the southwest and west. For 865 kilometres, it flows through or along the border with Germany before flowing into the North Sea via the Netherlands. Its most important German tributaries are the Neckar, Main, Moselle and Ruhr. The Rhine is of great economic importance and is one of the busiest waterways in Europe. The Danube drains almost the entire German Alpine foothills in the south for 647 kilometres and flows on to Austria and south-eastern Europe. Its most important German tributaries are the Iller, Lech, Isar and Inn. The Elbe, which rises in the Czech Republic, flows through eastern Germany for 725 kilometres. Its most important German tributaries are the Saale and Havel. For 179 kilometres, the Oder, as well as its most important tributary, the Neisse, is the border river to Poland. Only the catchment area of the 452-kilometre-long Weser lies entirely in Germany. It is fed by the Werra and Fulda rivers and drains the central north. The Ems flows for 371 kilometres through the extreme northwest of the country. Its catchment area also extends to parts of the Netherlands.
The natural lakes are predominantly of glacial origin. Therefore, most of the large lakes are found in the Alpine foothills, in Holstein Switzerland and in Mecklenburg. The largest lake belonging entirely to German territory is the Müritz, which is part of the Mecklenburg lake district. The largest lake with a German share is Lake Constance, which is also bordered by Austria and Switzerland. In western and eastern Germany there are many artificial lakes created by the recultivation of open-cast lignite mines or industrial wastelands, such as the Leipziger Neuseenland or the Dortmund Phoenix Lake.

Islands
The Frisian Islands are located in the Wadden Sea, directly off the Dutch, German and Danish coasts of the North Sea. While the North Frisian Islands are mainland remnants separated from the coast by land subsidence and subsequent flooding, the East Frisian Islands are barrier islands formed from sediments washed up by currents parallel to the coast as well as wave and tidal dynamics. Heligoland, located in the middle of the German Bight, is the furthest inhabited German island from the mainland. It dates back to the rise of a salt dome in the subsoil of the North Sea.
The largest German islands in the Baltic Sea are (from west to east) Fehmarn, Poel, Hiddensee, Rügen and Usedom. Rügen is also the largest German island. The largest peninsula is Fischland-Darß-Zingst. With the exception of Fehmarn, these land areas are part of a Bodden coast, i.e. a ground moraine landscape flooded after the ice age and subsequently modified by landfall processes.
The largest and best-known islands in inland waters are Reichenau, Mainau and Lindau in Lake Constance and Herreninsel in Lake Chiemsee.

Flora
The natural area of Germany lies in the temperate climate zone; from west to east, its natural vegetation marks the transition from a westerly lake climate to a continental climate. Without human influence, the flora would be mainly characterised by deciduous and mixed forests, with the exception of nutrient-poor or dry sites such as rocky outcrops, heathland lowlands and moorland, as well as the alpine and subalpine highlands, which are extremely poor in vegetation and cold temperate in their climate.
Locally, the flora in Germany shows a high degree of diversification due to site factors of the terrain and the mesoclimatic situation. The total stock of plant species living in the wild in Germany is estimated at over 9,500 species, of which almost 3,000 are seed plants, 74 fern plants, over 1,000 mosses and about 3,000 diatoms. In addition, there are about 14,000 species of fungi and 373 species of slime moulds. Particularly on fallow and disturbed areas, a number of introduced species can now be found, such as the black locust and the glandular touch-me-not.
Currently, forests cover 32 percent of the land area in Germany. This makes Germany one of the most densely forested countries in the European Union. The current tree species composition corresponds only to a small extent to natural conditions and is mainly determined by forestry. The most common tree species are the common spruce with 26.0 percent of the area, followed by the Scots pine with 22.9 percent, the copper beech with 15.8 percent and the oaks with 10.6 percent.
Around half of the state's land area is used for agriculture; according to the Federal Statistical Office, this amounted to 182,637 square kilometres on 31 December 2016. In addition to use as permanent grassland, arable farming has been practised on a large part of it, since the Stone Age or the Bronze Age predominantly with crops that do not occur naturally in Central Europe (most of the cereals from the Near East, potatoes and maize from America). In the river valleys, including those of the Main, Moselle, Ahr and Rhine, the landscape was often transformed for viticulture.
The preservation of nature is a public task in Germany and a state objective enshrined in Article 20a of the Basic Law. Nature conservation is served by 16 national parks (see National Parks in Germany), 19 biosphere reserves, 105 nature parks and thousands of nature reserves, landscape conservation areas and natural monuments.
Fauna
About 48,000 animal species have been recorded in Germany, including 104 mammal, 328 bird, 13 reptile, 22 amphibian and 197 fish species, as well as over 33,000 insect species, making the country "one of the more species-poor areas due to its geological history and geographical location". In addition to these species, there are over 1,000 crustaceans, almost 3,800 spiders, 635 molluscs and over 5,300 other invertebrates.
Wild mammals native to Germany include roe deer, wild boar, red and fallow deer, as well as foxes, martens and lynx. Beavers and otters are rare inhabitants of the floodplains, with some populations on the rise again. Alpine ibex, alpine marmot and chamois live in the Bavarian Alps; the latter can also be found in various low mountain ranges. Other large mammals that lived on the territory of present-day Germany in earlier times have been wiped out: Wild horse, aurochs (15th century), bison (16th century), brown bear (19th century), wolf (19th century), elk (20th century). While moose now occasionally migrate from neighbouring countries, wolves have re-established themselves firmly in Germany, coming from Poland, and gave birth to offspring for the first time around the turn of the millennium. In 2018, there were 73 documented wolf packs in Germany, most of which live in the states of Saxony, Brandenburg and Lower Saxony. In 2013, a herd of bison was released in the Rothaargebirge. In October 2019, a brown bear presumably migrating from Italy was photographed by a wildlife camera in the district of Garmisch-Partenkirchen. In the following months, the animal was detected again several times. In 2006, Bruno, the "problem bear", had already migrated to Germany. In the meantime, lynx, which were originally native to Germany, are living in Germany again, albeit in low population densities, because they are repeatedly the victims of poaching and road traffic.
The white-tailed eagle, which is considered the model for the German heraldic animal, is again found in about 500 pairs, mainly in Mecklenburg-Western Pomerania and Brandenburg. The golden eagle is now only found in the Bavarian Alps, where the bearded vulture from Switzerland and Austria, which had been eradicated there, is also making a comeback. The most common birds of prey today are the buzzard and the kestrel; the population of peregrine falcons is much smaller. More than half of the total population of red kites breeds in Germany, but is declining due to intensive agriculture. In contrast, many birds benefit from the presence of humans as cultural successors, especially urban pigeons, blackbirds (formerly forest birds), sparrows and titmice, whose survival is also ensured by winter feeding, as well as crows and gulls on rubbish tips. The Wadden Sea is a resting place for ten to twelve million migratory birds per year.
The salmon, which used to be common in the rivers, was largely wiped out in the course of industrialisation, but was reintroduced to the Rhine in the 1980s. In Germany, the last sturgeon was caught in 1969. Carp, introduced by the Romans, are kept in many ponds. The species of seal and grey seal - the latter the largest predator native to Germany - which were almost wiped out by professional fishermen in the mid-20th century as competitors for prey and are now protected, are now once again represented by a few thousand specimens on the German coasts. Eight species of cetaceans are found in the North Sea and Baltic Sea, including the harbour porpoise, and one species of dolphin, the common dolphin.
Reptiles living in Germany include grass snakes, adder and European pond turtle. Amphibians such as salamanders, frogs, toads, toads and newts are all on the Red List of threatened species in Germany.
The - partly invasive - neozoa in Germany include raccoon, raccoon dog, muskrat, nutria, collared parakeet, Canada goose and Egyptian goose.
Hunting
→ Main article: Hunting in Germany
In Germany, hunting is a subjective right connected to land ownership and is organised in a district hunting system. The most important game species in terms of the value of game and the damage caused by game in the forest and fields are roe deer and wild boar. Other game species relevant for hunting include red deer, mallard and brown hare. In Germany, there were almost 360,000 hunters in 2016/17. In 2019/2020, over 1.2 million roe deer were shot, and in 2019 just under 600,000 wild boar.
Human geography
Germany has a total of nine neighbouring countries: Germany borders Denmark to the north, Poland to the north-east, the Czech Republic to the east, Austria to the south-east, Switzerland to the south, France to the south-west, Luxembourg and Belgium to the west and the Netherlands to the north-west. The total border length is 3876 kilometres. This makes Germany the European country with the most neighbouring states.
In Germany, a total of 51 percent of the land area is used for agriculture (2016), forests cover another 30 percent. 14 percent is used as settlement and transport land. Water areas account for two per cent, and the remaining three per cent are distributed among other areas, mostly wasteland and also open-cast mines.
Administrative structure
The federally structured Federal Republic of Germany consists of 16 member states, officially known as Länder (federal states). The city states of Berlin and Hamburg each consist of unitary municipalities of the same name, while the Free Hanseatic City of Bremen, as the third city state, comprises two separate municipalities, Bremen and Bremerhaven. In contrast to other federal states, there are no federally independent territories in Germany.
The municipalities are the smallest democratically constituted, legally independent regional authorities and administrative units in Germany. They have a long tradition due to their cooperative character, which goes back to the Middle Ages. Today, with the exception of the city states and most independent cities, the municipalities in Germany are grouped into districts and other associations of municipalities. There are 401 territorial authorities at district level, of which 294 are districts and 107 are independent cities. They are subdivided into a total of 10,790 municipalities (as of January 2021), with a downward trend, as well as more than 200 largely uninhabited municipality-free areas. Districts and municipalities are subject to the municipal constitutional law of the respective federal state and are therefore organised differently throughout Germany. The district is thus both a supra-local local authority and a lower state administrative authority, it has its own representative body, the district council (Article 28 (1) sentence 2 GG), and performs various tasks of the "supra-local community" for the municipalities belonging to the district.
In terms of constitutional law, the municipalities are part of the Länder, which means that they are subject to their right of supervision and instruction and therefore have no sovereign power of their own. The guarantee of self-government in Article 28 (2) of the Basic Law - on the one hand a so-called institutional legal subject guarantee, from which it follows that there must be municipalities in the state structure at all, and on the other hand a subjective public right with constitutional rank - distinguishes between cities and municipalities, which are granted this right in its entirety, and municipal associations (counties), which are only granted it in a graded form. Thus, for the delimitation of tasks between municipalities and districts, there is a clear rule-exception relationship in favour of the municipalities (principle of subsidiarity). With regard to the "affairs of the local community", i.e. the power guaranteed in Article 28 (2) sentence 1 of the Basic Law to conduct business independently in this area of responsibility (so-called objective legal institution guarantee), the Federal Constitutional Court has established the primacy of the municipal level over the district level in accordance with the law: According to this, the principle of the "universality of the municipal sphere of action" applies to cities and municipalities "as an essential and identity-determining feature of municipal self-government", in contrast to the special competence of municipal associations by virtue of explicit legal allocation, with which there are also no fixed municipal association sovereignties.

Metropolitan areas
In Germany, densely populated areas and conurbations (agglomerations) are not precisely defined statistically. There are 81 large cities (100,000 inhabitants or more), 14 of which have more than 500,000 inhabitants, historically predominantly in the west and southwest of Germany. These agglomerations, which run along the Rhine, form the central part of the central European population concentration (blue banana). Most agglomerations are monocentric, whereas the Ruhr area is a (polycentric) conurbation. With its numerous centres, Germany does not have a primary city, unlike neighbouring countries such as Austria with its capital Vienna and Denmark with Copenhagen.
On the territory of Germany, eleven European metropolitan regions have been defined by the Conference of Ministers for Spatial Planning. These go far beyond the corresponding agglomerations. Cologne/Düsseldorf/Dortmund/Essen belong to the Rhine-Ruhr Metropolitan Region, Leipzig/Halle/Chemnitz to the Central German Metropolitan Region. Another is the Rhine-Neckar metropolitan region around Ludwigshafen/Mannheim/Heidelberg.
